Need some advice. I have a 2002 Jeep Wrangler Sport, 5 speed manual, 4.0L, lifted with 33 in tires. I want to regear from 3.73 to 4.56 to restore power going uphill in 5th gear. I've been making some phone calls to get estimates and have received the following information: parts (gear & pinion set for rear D44 and front D30 including master install kit) about $600 / labor (from shop that doesn't sell parts) front - $700, rear - $500, $1250 total. That comes to around $1850 total to regear. Seems high, but I'm told the shop doing the labor stands behind their work. Any recommendations? Should I order the parts myself online and if so, what specifically do I buy and where? Should I look for another shop to do the labor? Please help!
